According to coupler, deep sea equipment coaxial cable watertight interface is reached through coaxial underwater sealed cable, provides electric energy for deep sea equipment；
The DC high-voltage output end voltage that deck direct-current power output module is adjusted by deck DC power supply display control module, meets water
The DC high input voltage HDCVinput value of lower DC conversion module is between 295~305V, HDCVinput=HDCVoutput-
HDCIoutput*R, in which:
HDCVinput is underwater DC conversion module DC high input voltage,
DC high-voltage output end voltage of the HDCVoutput for deck direct-current power output module, unit V,
DC high-voltage output end electric current of the HDCIoutput for deck direct-current power output module, unit A,
R is myriametre coaxial cable or myriametre optoelectronic composite cable resistance；
Step2-3. system two-way communication:
(1) data upload:
Deep sea equipment detection data exports mixed signal through the coaxial cable watertight interface of deep sea equipment, reaches by coaxial underwater sealed cable
The coaxial cable watertight interface of underwater photoelectric communication dual-purpose relay unit, the modulation after underwater data coupler carries out Signal separator
Signal carries out electro-optic conversion into optical signal after the demodulation of underwater modem, through underwater optical transmitter and receiver, passes through optical fiber watertight
After interface and optical fiber watertight cable reach the optical fiber interface of the oil-filled box in deep-sea, detection data is uploaded to by deck by optoelectronic composite cable
Unit optical fiber interface carries out photoelectric conversion into electric signal through deck optical transmitter and receiver, is taken by deck serial server I or deck serial ports
Business device II shows the detection data that deep sea equipment uploads in deck display and control terminal；
(2) instruction issuing:
It is instructed by deck display and control terminal input control, through deck serial server I or deck serial server II by deck light
Terminal carries out electro-optic conversion into optical signal, through optical fiber interface, carries out Signal separator through the oil-filled box in deep-sea by optoelectronic composite cable, arrives
The oil-filled box optical fiber interface in deep-sea, the optical fiber watertight interface of underwater photoelectric communication dual-purpose relay unit is connected to through optical fiber watertight cable,
Being lauched terminal photoelectric conversion through light is that electric signal mixes after being modulated by underwater modem through underwater data coupler, is passed through
Coaxial cable watertight interface reaches deep sea equipment coaxial cable watertight interface by coaxial underwater sealed cable, demodulates and controlled through deep sea equipment
The control to deep sea equipment is completed in system instruction.
